DOP & Epoxy

Plasticiser are low molecular weight substances that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture. Plasticizers are added to a polymer solution to promote its plasticity and flexibility.

Plasticizers are colourless and odourless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride), plasticizers soften the PVC to make it flexible and bendable.

Plasticizers available at SNG Microns Private Limited

Epoxidized soybean oil (ESBO) Di-n-octyl phthalate (DOP)

Epoxidized soybean oil (ESBO)

Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid. Commonly known as epoxy oil in PVC pipe & fittings industry.

ESBO is used as a co-stabilizer and plasticizer in flexible as well as rigid PVC applications. It not only improves colour hold but also increases weathering properties. Our ESBO can be used in various applications such as Pipe, wires and cables and rigid extruded products to enhance thermal and aesthetic properties.

Typical property of Epoxidized soybean oil (ESBO)

Parameters Specification Our Grade

Our grades of Epoxidized soybean oil (ESBO) are having much better quality than standard specification as given above in table. We suggest customers to check the technical data sheet (TDS) of product before placing order to suppliers to optimize their production and to get complete benefits of original products.

Di-n-octyl phthalate (DOP)
Di-n-octyl phthalate appears as a clear liquid with a mild odour. Slightly less dense than water and insoluble in water. Hence floats on water. Di-n-octyl phthalate is a colourless, odourless, oily liquid that doesn’t evaporate easily. It is a man-made substance used to keep plastics soft or more flexible. This type of plastic can be used for PVC Pipe, medical tubing and blood storage bags, wire and cables, carpet back coating, floor tile, and adhesives. It is also used in cosmetics and pesticides.

The mixing of polyvinyl chloride (PVC) with dioctyl phthalate (DOP) shows two stages of gelation and fusion, but the homogeneity of each stage is influenced by the thermal stability of PVC and its rheological behaviour. Hence help in making pipe soft or more flexible.

Why Other plasticizer are cheaper Or Another supplier offering at cheaper rate?

World produces various type of plasticizers for varies industries, all the plasticizers produced across globe or in India are not same, based on physical and chemicals property, different plasticizers get used in different applications. Similarly for PVC Pipe, fittings or plastic industry there are many plasticizers available in the market for applications. In-fact the “filler” of plasticizer is also available in market which are cheap, low- cost, of inferior quality. While buying, you could observe that on drum of plasticizer either “Plasticizer” is mentioned or nothing is mentioned as product name or something else is mentioned on packetizing or invoice.

Very few suppliers offer DOP or Epoxidized soybean oil. The trick in the market is that when customer place an order for DOP or Epoxidized soybean oil, suppliers accept the order and they supply just any plasticizer, which are generally “filler” of plasticizers and of lower quality. However, suppliers offer just slightly lower price quotation so that customer can not judge of quality based on price, We at SNG Microns Pvt Ltd receive almost daily inquiry on our price of DOP and Epoxidized soybean oil being much higher but we know that supplier offered lower price to customers are not supplying the original DOP or Epoxidized soybean oil as per technical standards, they are just supplying any plasticizers.

Not only, what we have mentioned above, it is also that supplier is billing DOP and Epoxidized soybean oil in invoice but giving the customer Chlorinated Paraffin Oil (CPW) oils, which is much cheaper compare to DOP and Epoxy.

Where to buy from ESBO and DOP
We are one of the largest suppliers of ESBO and DOP, you could blindly trust us on quality of products and price.
